Energy balance

Short-term cold acclimation does not significantly increase non-shivering thermogenesis (NST) or energy expenditure in obese men, despite recruiting BAT.

While cold exposure recruits brown fat in obese individuals, it may not significantly increase your calorie burning (energy expenditure) compared to lean individuals. This means cold acclimation might not be a powerful weight-loss tool on its own for obese people, even if it improves metabolic health.

Why this rating

Small sample size and high variability in NST response (9.7±9.1% vs 13.8±8.9%) limit the strength of the conclusion.
